[0002] The invention provides 4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine compounds and
4,5,6,7-tetrahydro-2H-pyrazolo[4,3-c]pyridine compounds, the use thereof for inhibiting

(including, but not limited to, TLR7/8, TLR7/8/9, TLR7/9, and TLR8/9), the use thereof
for inhibiting an endosomal Toll-like receptor (e.g. TLR7, TLR8 or TLR9) pathway,
and any combinations thereof, and methods of treating autoimmune diseases using such
compounds.
BACKGROUND OF THE INVENTION
[0003] Early detection of specific classes of pathogens is accomplished by the innate immune
system with the help of pattern recognition receptors (PRRs). Toll-like receptors
(TLRs) are pattern recognition receptors which play an essential role in the innate
immunity, by recognizing invasion of microbial pathogens and initiating intracellular
signal transduction pathways to trigger expression of genes, the products of which
can control innate immune responses. There are 10 TLRs in the human genome, where
TLR1, TLR2, TLR4, TLR5, and TLR6 respond to extracellular stimuli, while TLR3, TLR7,
TLR8, and TLR9 respond to intracytoplasmic pathogen associated molecular patterns
(PAMPs), being associated with the endolysosomal compartment.
[0004] Toll-like receptors recognize pathogens associated molecular patterns present in
molecules that are broadly shared by pathogens but are structurally distinct from
host molecules. The ligands for these receptors are highly conserved microbial molecules
such as lipopolysaccharides (LPS) (recognized by TLR4), lipopeptides (TLR2 in combination
with TLR1 or TLR6), flagellin (TLR5), single-stranded RNA (TLR7 and TLR8), double-stranded
RNA (TLR3), CpG motif-containing DNA (recognized by TLR9), and profilin present on
uropathogenic bacteria (TLR 11). Thus cell-surface TLR dimers including TLR4-MD-2,
TLR1-TLR2, and TLR6-TLR2 recognize microbial membrane lipids, whereas the endosomal
Toll-like receptors TLR3, TLR7, TLR8, and TLR9 reside in intracellular organelles
and recognize microbial nucleic acids.
[0005] TLR7, TLR8, and TLR9 belong to a subfamily of TLRs based on their genomic structure,
sequence similarities, and homology. TLR7, TLR8, and TLR9 are located in intracellular
endolysosomal compartments and show a unique pattern of cell type-specific expression
that is thought to be responsible for different pathogen response profiles.
[0006] In addition to recognizing foreign material, TLRs can mistakenly respond to self
products and cause autoimmune diseases. TLR7 and 9, innate immune sensors for microbial
RNA or DNA, respectively, have been implicated in autoimmune diseases such as psoriasis
(see
Lande et al., "Plasmacytoid dendritic cells sense self-DNA coupled with antimicrobial
peptide", Nature 449, pp 564-569, 2007), arthritis (see
Asagiri et al., "Cathepsin K-dependent toll-like receptor 9 signaling revealed in
experimental arthritis", Science 319, pp 624-627, 2008), and systemic lupus erythematosus (SLE) (see
Pisitkun, P. et al. "Autoreactive B cell responses to RNA-related antigens due to
TLR7 gene duplication", Science 312, pp 1669-72, 2006;

autoimmunity and dendritic cell proliferation", Immunity, 27, pp 801-10, 2007;

and have opposing inflammatory and regulatory roles in a murine model of lupus", Immunity

Ehlers, M., et al. "TLR9/MyD88 signaling is required for class switching to pathogenic
IgG2a and 2b autoantibodies in SLE", J. Exp. Med. 203, pp 553-561, 2006;

role of toll-like receptors in the development of chronic inflammatory disease", Annu.
Rev. Immunol., 25, pp 419-441, 2007).
[0007] It has been shown that autoimmunity is exacerbated by the aberrant trafficking of
self nucleic acids to endolysosomes (see Lande et al., 2007; Marshak-Rothstein and
Rifkin, 2007; and
Leadbetter et al., "Chromatin-IgG complexes activate B cells by dual engagement of
IgM and Toll-like receptors", Nature, 416, pp 603-607, 2002). In autoimmune diseases like SLE, self-RNA and self-DNA are complexed with autoantibodies
against the nucleic acid or nucleoproteins, delivered into endosomal compartments
via FcgRII-mediated endocytosis, leading to dendritic cell (DC) activation and production
of type I interferon (IFN) (
Barrat et al., "Nucleic acids of mammalian origin can act as endogenous ligands for
Toll-like receptors and may promote systemic lupus erythematosus", J. Exp. Med. 202,
pp 1131-1139, 2005). While in psoriasis, self-DNA and -RNA form complexes with the cationic antimicrobial
peptide LL37, gain access to TLR7 and 9 in endolysosomes of DCs, and induce aberrant
production of IFN-a (
Ganguly et al., "Self-RNA-antimicrobial peptide complexes activate human dendritic
cells through TLR7 and TLR8", J. Exp. Med. 206, pp 1983-1994, 2009; and Lande et al., 2007). In rheumatoid arthritis (RA) the synovial membrane is infiltrated
by activated immune cells, predominantly macrophages and T cells, resulting in the
chronic production of proinflammatory cytokines and matrix metalloproteinases. TNF
plays a central role in RA and the inhibition of TLR8 has been shown to inhibit TNF
production (see
Sandra M. Sacre et al. "Inhibitors of TLR8 Reduce TNF Production from Human Rheumatoid
Synovial Membrane Cultures", J. Immun., 81, pp 8002-8009, 2008).
[0008] Because of their association with autoimmune diseases, it has been suggested that
TLR7, TLR8 and TLR9 are important therapeutic targets for the treatment of systemic
lupus erythematosus, rheumatoid arthritis, psoriasis and other autoimmune diseases.

[0039] The terms "combination" or "pharmaceutical combination," as used herein mean a product
that results from the mixing or combining of more than one active ingredient and includes
both fixed and non-fixed combinations of the active ingredients. The term "fixed combination"
means that the active ingredients, by way of example, a compound of the invention
and one or more additional therapeutic agent, are administered to a subject simultaneously
in the form of a single entity or dosage. The term "non-fixed combination" means that
the active ingredients, by way of example, a compound of of the invention and one
or more additional therapeutic agent, are administered to a subject as separate entities
either simultaneously, concurrently or sequentially with no specific time limits,
wherein such administration provides therapeutically effective levels of the active
ingredients in the body of the subject. The latter also applies to cocktail therapy,
e.g. the administration of 3 or more active ingredients.
[0040] The terms "composition" or "pharmaceutical composition," as used herein, refers to
a mixture of a compound of the invention with at least one and optionally more than
one other pharmaceutically acceptable chemical components, such as carriers, stabilizers,
diluents, dispersing agents, suspending agents, thickening agents, and/or excipients.
[0041] As used herein, the term "inhibit", "inhibition" or "inhibiting" refers to the reduction
or suppression of a given condition, symptom, or disorder, or disease, or a significant
decrease in the baseline activity of a biological activity or process.
[0042] The term "an optical isomer" or "a stereoisomer", as used herein, refers to any of
the various stereo isomeric configurations which may exist for a given compound of
the present invention and includes geometric isomers. It is understood that a substituent
may be attached at a chiral center of a carbon atom. The term "chiral" refers to molecules
which have the property of non-superimposability on their mirror image partner, while
the term "achiral" refers to molecules which are superimposable on their mirror image
partner. Therefore, the invention includes enantiomers, diastereomers or racemates
of the compound. "Enantiomers" are a pair of stereoisomers that are non- superimposable
mirror images of each other. A 1:1 mixture of a pair of enantiomers is a "racemic"
mixture. The term is used to designate a racemic mixture where appropriate. "Diastereoisomers"
are stereoisomers that have at least two asymmetric atoms, but which are not mirror-images
of each other. The absolute stereochemistry is specified according to the Cahn- Ingold-
Prelog R-S system. When a compound is a pure enantiomer the stereochemistry at each
chiral carbon may be specified by either R or S. Resolved compounds whose absolute
configuration is unknown can be designated (+) or (-) depending on the direction (dextro-
or levorotatory) which they rotate plane polarized light at the wavelength of the
sodium D line. Certain compounds described herein contain one or more asymmetric centers
or axes and may thus give rise to enantiomers, diastereomers, and other stereoisomeric
forms that may be defined, in terms of absolute stereochemistry, as (R)- or (S)-.
[0043] The term "pharmaceutically acceptable carrier", as used herein, includes any and
all solvents, dispersion media, coatings, surfactants, antioxidants, preservatives
(e.g., antibacterial agents, antifungal agents), isotonic agents, absorption delaying
agents, salts, preservatives, drug stabilizers, binders, excipients, disintegration
agents, lubricants, sweetening agents, flavoring agents, dyes, and the like and combinations
thereof, as would be known to those skilled in the art (see, for example,
Remington's Pharmaceutical Sciences, 18th Ed. Mack Printing Company, 1990, pp. 1289-
1329). Except insofar as any conventional carrier is incompatible with the active ingredient,
its use in the therapeutic or pharmaceutical compositions is contemplated.
[0044] The term "pharmaceutically acceptable salt," as used herein, refers to a salt which
does not abrogate the biological activity and properties of the compounds of the invention,
and does not cause significant irritation to a subject to which it is administered.
[0045] The term "subject", as used herein, encompasses mammals and non-mammals. Examples
of mammals include, but are not limited to, humans, chimpanzees, apes, monkeys, cattle,
horses, sheep, goats, swine, rabbits, dogs, cats, rats, mice, guinea pigs, and the
like. Examples of non-mammals include, but are not limited to, birds, fish and the
like. Frequently the subject is a human, and may be a human who has been diagnosed
as in need of treatment for a disease or disorder associated with the activity of
an endosomal Toll-like receptor (e.g. TLR7, TLR8 or TLR9) and any combinations thereof
(including, but not limited to, TLR7/8, TLR7/8/9, TLR7/9, and TLR8/9), or associated
with an endosomal Toll-like receptor (e.g. TLR7, TLR8 or TLR9) pathway, and any combinations.
[0046] The term "a subject in need of such treatment", refers to a subject which would benefit
biologically, medically or in quality of life from such treatment.
[0047] The term "therapeutically effective amount," as used herein, refers to an amount
of a compound of the present invention that will elicit the biological or medical
response of a subject, for example, reduction or inhibition of an enzyme or a protein
activity, or ameliorate symptoms, alleviate conditions, slow or delay disease progression,
or prevent a disease, etc. In one non-limiting embodiment, the term "a therapeutically
effective amount" refers to the amount of the compound of the present invention that,
when administered to a subject, is effective to (1) at least partially alleviate,
inhibit, prevent and/or ameliorate a condition, or a disorder or a disease (i) mediated
by an endosomal Toll-like receptor (e.g. TLR7, TLR8 or TLR9) and any combinations
thereof (including, but not limited to, TLR7/8, TLR7/8/9, TLR7/9, and TLR8/9), or
mediated by an endosomal Toll-like receptor (e.g. TLR7, TLR8 or TLR9) pathway, and
any combinations thereof or (ii) associated with an endosomal Toll-like receptor (e.g.
TLR7, TLR8 or TLR9) and any combinations thereof (including, but not limited to, TLR7/8,
TLR7/8/9, TLR7/9, and TLR8/9), or associated with an endosomal Toll-like receptor
(e.g. TLR7, TLR8 or TLR9) pathway, and any combinations thereof, or (iii) characterized
by activity (normal or abnormal) of an endosomal Toll-like receptor (e.g. TLR7, TLR8
or TLR9) and any combinations thereof (including, but not limited to, TLR7/8, TLR7/8/9,
TLR7/9, and TLR8/9); or (2) reduce or inhibit the activity of an endosomal Toll-like
receptor (e.g. TLR7, TLR8 or TLR9) and any combinations thereof (including, but not
limited to, TLR7/8, TLR7/8/9, TLR7/9, and TLR8/9); or (3) reduce or inhibit the expression
of an endosomal Toll-like receptor (e.g. TLR7, TLR8 or TLR9) and any combinations
thereof (including, but not limited to, TLR7/8, TLR7/8/9, TLR7/9, and TLR8/9). In
another non-limiting embodiment, the term "a therapeutically effective amount" refers
to the amount of the compound provided herein that, when administered to a cell, or
a tissue, or a non-cellular biological material, or a medium, is effective to at least
partially reducing or inhibiting the activity of an endosomal Toll-like receptor (e.g.
TLR7, TLR8 or TLR9) and any combinations thereof (including, but not limited to, TLR7/8,
TLR7/8/9, TLR7/9, and TLR8/9), or inhibiting the activity of an endosomal Toll-like
receptor (e.g. TLR7, TLR8 or TLR9) pathway, and any combinations thereof.

[0157] Any formula given herein is also intended to represent unlabeled forms as well as
isotopically labeled forms of the compounds. Isotopically labeled compounds have structures
depicted by the formulas given herein except that one or more atoms are replaced by
an atom having a selected atomic mass or mass number. Examples of isotopes that can
be incorporated into compounds of the invention include isotopes of hydrogen, carbon,
nitrogen, oxygen, phosphorous, fluorine, and chlorine, such as
2H,
3H,
11C,
13C,
14C,
15N,
18F
31P,
32P,
35S,
36Cl,
123I,
124I,
125I respectively. The invention includes various isotopically labeled compounds as defined
herein, for example those into which radioactive isotopes, such as
3H and
14C, or those into which non-radioactive isotopes, such as
2H and
13C are present. Such isotopically labelled compounds are useful in metabolic studies
(with
14C), reaction kinetic studies (with, for example
2H or
3H), detection or imaging techniques, such as positron emission tomography (PET) or
single-photon emission computed tomography (SPECT) including drug or substrate tissue
distribution assays, or in radioactive treatment of patients. In particular, an
18F or labeled compound may be particularly desirable for PET or SPECT studies. Isotopically-labeled
compounds of formula (I) can generally be prepared by conventional techniques known
to those skilled in the art or by processes analogous to those described in the accompanying
Examples and Preparations using an appropriate isotopically-labeled reagents in place
of the non-labeled reagent previously employed.
[0158] Further, substitution with heavier isotopes, particularly deuterium (i.e.,
2H or D) may afford certain therapeutic advantages resulting from greater metabolic
stability, for example increased in vivo half-life or reduced dosage requirements
or an improvement in therapeutic index. It is understood that deuterium in this context
is regarded as a substituent of a compound of the formula (I). The concentration of
such a heavier isotope, specifically deuterium, may be defined by the isotopic enrichment
factor. The term "isotopic enrichment factor" as used herein means the ratio between
the isotopic abundance and the natural abundance of a specified isotope. If a substituent
in a compound of this invention is denoted deuterium, such compound has an isotopic
enrichment factor for each designated deuterium atom of at least 3500 (52.5% deuterium
incorporation at each designated deuterium atom), at least 4000 (60% deuterium incorporation),
at least 4500 (67.5% deuterium incorporation), at least 5000 (75% deuterium incorporation),
at least 5500 (82.5% deuterium incorporation), at least 6000 (90% deuterium incorporation),
at least 6333.3 (95% deuterium incorporation), at least 6466.7 (97% deuterium incorporation),
at least 6600 (99% deuterium incorporation), or at least 6633.3 (99.5% deuterium incorporation).
[0159] Pharmaceutically acceptable solvates in accordance with the invention include those
wherein the solvent of crystallization may be isotopically substituted,
e.g. D
2O, d
6-acetone, d
6-DMSO.
[0160] Compounds of the invention that contain groups capable of acting as donors and/or
acceptors for hydrogen bonds may be capable of forming co-crystals with suitable co-crystal
formers. These co-crystals may be prepared from compounds of the invention by known
co-crystal forming procedures. Such procedures include grinding, heating, co-subliming,
comelting, or contacting in solution compounds of the invention with the co-crystal
former under crystallization conditions and isolating co-crystals thereby formed.
Suitable co-crystal formers include those described in
WO 2004/078163. Hence the invention further provides co-crystals comprising a compound of Formula
(A), Formula (I), Formula (II), Formula (Ia to Ip) and Formula (IIa to IIk).
[0161] All methods described herein can be performed in any suitable order unless otherwise
indicated herein or otherwise clearly contradicted by context. The use of any and
all examples, or exemplary language (e.g. "such as") provided herein is intended merely
to better illuminate the invention and does not pose a limitation on the scope of
the invention otherwise claimed.
[0162] Any asymmetric atom (e.g., carbon or the like) of the compound(s) of the present
invention can be present in racemic or enantiomerically enriched, for example the
(
R)-, (
S)- or (
R,
S)-configuration. In certain embodiments, each asymmetric atom has at least 50 % enantiomeric
excess, at least 60 % enantiomeric excess, at least 70 % enantiomeric excess, at least
80 % enantiomeric excess, at least 90 % enantiomeric excess, at least 95 % enantiomeric
excess, or at least 99 % enantiomeric excess in the (
R)- or (
S)- configuration. Substituents at atoms with unsaturated double bonds may, if possible,
be present in
cis- (
Z)- or
trans- (
E)- form.
[0163] Accordingly, as used herein a compound of the present invention can be in the form
of one of the possible isomers, rotamers, atropisomers, tautomers or mixtures thereof,
for example, as substantially pure geometric (
cis or
trans) isomers, diastereomers, optical isomers (antipodes), racemates or mixtures thereof.
[0164] Any resulting mixtures of isomers can be separated on the basis of the physicochemical
differences of the constituents, into the pure or substantially pure geometric or
optical isomers, diastereomers, racemates, for example, by chromatography and/or fractional
crystallization. Any resulting racemates of final products or intermediates can be
resolved into the optical antipodes by known methods,
e.g., by separation of the diastereomeric salts thereof, obtained with an optically active
acid or base, and liberating the optically active acidic or basic compound. In particular,
a basic moiety may thus be employed to resolve the compounds of the present invention
into their optical antipodes,
e.g., by fractional crystallization of a salt formed with an optically active acid,
e.g., tartaric acid, dibenzoyl tartaric acid, diacetyl tartaric acid, di-
O,
O'-
p-toluoyl tartaric acid, mandelic acid, malic acid or camphor-10-sulfonic acid. Racemic
products can also be resolved by chiral chromatography,
e.g., high pressure liquid chromatography (HPLC) using a chiral adsorbent.
[0165] Furthermore, the compounds of the present invention, including their salts, can also
be obtained in the form of their hydrates, or include other solvents used for their
crystallization. The compounds of the present invention may inherently or by design
form solvates with pharmaceutically acceptable solvents (including water); therefore,
it is intended that the invention embrace both solvated and unsolvated forms. The
term "solvate" refers to a molecular complex of a compound of the present invention
(including pharmaceutically acceptable salts thereof) with one or more solvent molecules.
Such solvent molecules are those commonly used in the pharmaceutical art, which are
known to be innocuous to the recipient, e.g., water, ethanol, and the like. The term
"hydrate" refers to the complex where the solvent molecule is water.
[0166] The compounds of the present invention, including salts, hydrates and solvates thereof,
may inherently or by design form polymorphs.
Processes for Making Compounds of Formula (A) and subformulae thereof
[0167] General procedures for preparing compounds of Formula (A), Formula (I), Formula (II),
Formula (Ia to Ip) and Formula (IIa to IIk) are described herein. In the reactions
described, reactive functional groups, for example hydroxy, amino, imino, thio or
carboxy groups, where these are desired in the final product, may be protected to
avoid their unwanted participation in the reactions. Within the scope of this text,
only a readily removable group that is not a constituent of the particular desired
end product of the compounds of the present invention is designated a "protecting
group", unless the context indicates otherwise. The protection of functional groups
by such protecting groups, the protecting groups themselves, and their cleavage reactions
are described for example in standard reference works, such as
J. F. W. McOmie, "Protective Groups in Organic Chemistry", Plenum Press, London and
New York 1973, in
T. W. Greene and P. G. M. Wuts, "Protective Groups in Organic Synthesis", Third edition,
Wiley, New York 1999, in "
The Peptides"; Volume 3 (editors: E. Gross and J. Meienhofer), Academic Press, London
and New York 1981, in "
Methoden der organischen Chemie" (Methods of Organic Chemistry), Houben Weyl, 4th
edition, Volume 15/l, Georg Thieme Verlag, Stuttgart 1974, in
H.-D. Jakubke and H. Jeschkeit, "Aminosäuren, Peptide, Proteine" (Amino acids, Peptides,
Proteins), Verlag Chemie, Weinheim, Deerfield Beach, and Basel 1982, and in
Jochen Lehmann, "Chemie der Kohlenhydrate: Monosaccharide und Derivate" (Chemistry
of Carbohydrates: Monosaccharides and Derivatives), Georg Thieme Verlag, Stuttgart
1974. A characteristic of protecting groups is that they can be removed readily (i.e.
without the occurrence of undesired secondary reactions) for example by solvolysis,
reduction, photolysis or alternatively under physiological conditions (e.g. by enzymatic
cleavage).
[0168] Compounds of Formula (A), Formula (I), Formula (II), Formula (Ia to Ip) or Formula

of Formula (Ia) or Formula (IIa), respectively, where R
1 is NH
2. Further alkylation or acylation results in compounds of Formula (Ia) or Formula
(IIa), where R
1 is as further defined herein.

[0170] In additional embodiments, compounds of Formual (A), Formula (I) and Formula (II)
can be obtained by replacing intermediate (Int-1) with either intermediates Int-2,
Int-3, Int-4, Int-5, Int-6, Int-7, Int-8, Int-9, Int-10 or Int-11, resulting compounds

of 4-((5-(1,6-dimethyl-1H-pyrazolo[3,4-b]pyridin-4-yl)-3-methyl-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridin-1-yl)methyl)bicyclo[2.2.2]octan-1-amine
(Compound No. 1) in DCM was added HATU (41.8 mg, 0.11 mmol) and DIPEA (25.8 mg, 0.035 mL, 0.2 mmol).
The resulting mixture was then stirred at rt for 1 hr then loaded to a 4 g silica
gel column and was eluted with 0-50% IPA (containing 0.02 M of ammonia) in DCM. Collected
fractions and concentrated. The residue was dissolved in 2 mL of DCE, azetidin-3-ol

Administration and Pharmaceutical Compositions
[0317] For the therapeutic uses of compounds of the invention, such compounds are administered
in therapeutically effective amounts either alone or as part of a pharmaceutical composition.
Accordingly, the present invention provides a pharmaceutical composition, which comprises
a compound of the invention, or pharmaceutically acceptable salt thereof, and one
or more pharmaceutically acceptable carriers, diluents, or excipients. For purposes
of the present invention, unless designated otherwise, solvates and hydrates are generally
considered compositions. Preferably, pharmaceutically acceptable carriers are sterile.
[0318] The pharmaceutical composition of the present invention can be in unit dosage of
about 1-1000 mg of active ingredient(s) for a subject of about 50-70 kg. The therapeutically
effective dosage of a compound, the pharmaceutical composition, or the combinations
thereof, is dependent on the species of the subject, the body weight, age and individual
condition, the disorder or disease or the severity thereof being treated. A physician,
clinician or veterinarian of ordinary skill can readily determine the effective amount
of each of the active ingredients necessary to prevent, treat or inhibit the progress
of the disorder or disease.
[0319] The above-cited dosage properties are demonstrable
in vitro and
in vivo tests using advantageously mammals, e.g., mice, rats, dogs, monkeys or isolated organs,
tissues and preparations thereof. The compounds of the present invention can be applied
in vitro in the form of solutions,
e.g., aqueous solutions, and
in vivo either enterally, parenterally, advantageously intravenously,
e.g., as a suspension or in aqueous solution. The dosage
in vitro may range between about 10
-3 molar and 10
-9 molar concentrations. A therapeutically effective amount
in vivo may range depending on the route of administration, between about 0.1-500 mg/kg.
[0320] The activity of a compound according to the present invention can be assessed by
the following
in vitro &
in vivo methods.
[0321] The pharmaceutical compositions of the invention can be prepared using processes
which include admixing a compound of the invention, or pharmaceutically acceptable
salts thereof, with one or more pharmaceutically acceptable carriers, diluents or
excipients. By way of example, the pharmaceutical compositions of the inventions are
manufactured by mixing, granulating and/or coating methods using a compound of the
invention in free form, or in a pharmaceutically acceptable salt form, in association
with at least one pharmaceutically acceptable carrier, diluent or excipient.
[0322] The present invention further provides anhydrous pharmaceutical compositions and
dosage forms comprising the compounds of the present invention as active ingredients,
since water may facilitate the degradation of certain compounds.
[0323] Anhydrous pharmaceutical compositions and dosage forms of the invention can be prepared
using anhydrous or low moisture containing ingredients and low moisture or low humidity
conditions. An anhydrous pharmaceutical composition may be prepared and stored such
that its anhydrous nature is maintained. Accordingly, anhydrous compositions are packaged
using materials known to prevent exposure to water such that they can be included
in suitable formulary kits. Examples of suitable packaging include, but are not limited
to, hermetically sealed foils, plastics, unit dose containers (e. g., vials), blister
packs, and strip packs.
[0324] The invention further provides pharmaceutical compositions and dosage forms that
comprise one or more agents that reduce the rate by which the compound of the present
invention as an active ingredient will decompose. Such agents, which are referred
to herein as "stabilizers," include, but are not limited to, antioxidants such as
ascorbic acid, pH buffers, or salt buffers, etc.
[0325] The pharmaceutical composition can be formulated for particular routes of administration
such as oral administration, rectal administration, transdermal administration, parenteral,
intravenous administration, intramuscular administration, pulmonary administration,
inhalation administration, intranasal administration, ophthalmic administration and
topical administration.
Oral Administration Dosage Forms
[0326] The pharmaceutical compositions of the invention can be administered orally as discrete
dosage forms, wherein such dosage forms include, but are not limited to, capsules,
gelatin capsules, caplets, tablets, chewable tablets, lozenges, dispersible powders,
granules, syrups, flavored syrups, solutions or suspensions in aqueous or non-aqueous
liquids, edible foams or whips, and oil-in-water liquid emulsions or water-in-oil
liquid emulsions.
[0327] Accordingly, for oral administration the pharmaceutical compositions of the invention
comprising an effective amount of a compound of the invention can be made up in a
solid form (including without limitation capsules, gelatin capsules, hard or soft
capsules, tablets, chewable tablets, lozenges, caplets, pills, granules or dispersible
powders), or in a liquid form (including without limitation solutions, aqueous or
oily suspensions, syrups, elixirs, foams, whips or emulsions). The pharmaceutical
compositions can be subjected to conventional pharmaceutical operations such as sterilization
and/or can contain conventional inert diluents, lubricating agents, or buffering agents,
as well as adjuvants, such as preservatives, stabilizers, wetting agents, emulsifiers
and buffers, etc.
[0328] Compositions intended for oral use are prepared according to any method known in
the art for the manufacture of pharmaceutical compositions and such compositions can
contain one or more agents selected from the group consisting of sweetening agents,
flavoring agents, coloring agents and preserving agents in order to provide pharmaceutically
elegant and palatable preparations.
[0329] Typically, the pharmaceutical compositions are tablets or gelatin capsules comprising
the active ingredient together with one or more of:
- a) diluents, e.g., lactose, dextrose, sucrose, mannitol, sorbitol, cellulose and/or
glycine;
- b) lubricants, e.g., silica, talcum, stearic acid, its magnesium or calcium salt and/or
polyethyleneglycol; for tablets also
- c) binders, e.g., magnesium aluminum silicate, starch paste, gelatin, tragacanth, methylcellulose,
sodium carboxymethylcellulose and/or polyvinylpyrrolidone; if desired
- d) disintegrants, e.g., starches, agar, alginic acid or its sodium salt, or effervescent mixtures; and
- e) absorbents, colorants, flavors and sweeteners.
[0330] Tablets may contain the active ingredient in admixture with nontoxic pharmaceutically
acceptable excipients which are suitable for the manufacture of tablets. These excipients
are, for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose,
calcium phosphate or sodium phosphate; granulating and disintegrating agents, for
example, corn starch, or alginic acid; binding agents, for example, starch, gelatin

Assays
[0401] Compounds of the invention were assayed in the assays described in the following
paragraphs.
Test Compound Preparation
[0402] Compounds were generally serially diluted (1/3) in DMSO and plated on sterile 384
well tissue culture plates and stored until ready for use. Each ten-point dilution
was typically plated in triplicate in parallel rows.
TLR7, TLR8 and TLR9 Antagonist Assays in human PBMC's
PBMC Isolation
[0403] Fresh blood was collected from normal human donors under written informed consent
in heparinized syringes on the morning of the assay. The blood was diluted in RPMI-1640
medium and the white blood cells were separated from red blood cells by centrifugation
(800g 15' 0 acceleration, 0 brake) on a Ficoll cushion. Peripheral blood mononuclear
cells (PBMCs) were separated from platelets by a series of low-speed centrifugations
(1000RPM 10') in PBS+5% HI-FBS and 1mM EDTA. Purified PBMCs were re-suspended in assay
medium (RPMI-1640 w Glutamax (Invitrogen) supplemented with 5% HI-FBS, 10mM HEPES,
50uM β-mercaptoethanol, and 100mG/L penicillin/streptomycin cocktail). Viable PBMCs
were counted on a hemacytometer and kept on ice until ready for plating.
Agonist Treatment Bulk Transfection
[0404] A 4X concentration (4 ug/ml or 40ug/ml for TLR8 or TLR7 assays, respectively) of
the TLR7/8 agonist ssRNA40 (IDT) was complexed with 10% DOTAP (Roche) in assay medium
for 30 min prior to addition to the PBMC suspension (5 million cells/ml). After addition,
the final concentration of ssRNA40 in the TLR7/8 stimulated PBMC suspension was 1
µg/ml for TLR8 assay, and 10µg/mL for the TLR7 assay. The final DOTAP concentration
was 2.5%.
[0405] Diluted PBMCs (5 million cells/ml) were treated with with 4X TLR9 agonist ODN2216
(Invivogen). Final concentration of ODN2216 in TLR9 stimulated PBMC suspension was
0.3µM.
PBMC Plating and Compound Treatment
[0406] Agonist stimulated PBMCs were plated on the compound treated 384 well plates at 150,000
cells/well. Un-stimulated PBMCs were plated as controls on each plate. Plating volume
was 40µL per well. DMSO concentration in each well was 0.25%.
[0407] A separate plate, without compounds, with titrations of ssRNA40 and ODN2216 was included
in every assay to measure agonist response of each donor's PBMC prep. Assay plates
were placed in a tissue culture incubator (37°C, 5%CO
2) for 14-16 hrs. After this incubation, the plates were centrifuged and stored at
-20°C until they were assayed.
IL-6 TR-FRET Assay for TLR8 activity:
[0408]
- 1) Cisbio Human IL-6 kit, 20,000 tests (62TNFPEC), and GNF High-Base TC 384 well plates
(cat # 789163G) were used;
- 2) the Anti-TIL-6 Cryptate conjugate and the Anti-IL-6 XL665 conjugate were diluted
1:20 in Reconstitution Buffer;
- 3) a 1:1 mixture of 3 µl/well Anti-IL-6 Cryptate conjugate and 3 µl/well Anti-IL-6
XL665 conjugate was prepared;
- 4) 6µl/well HTRF dilution mastermix was added to 6 µl of transferred supernatant samples
in proxiplates;
- 5) The plates were incubated for 3 hrs at rt in the dark; and
- 6) the levels of IL-6 production was measured using an Envision plate reader (665nm
(emmission)/590nm (excitation)) with HTRF settings and ratiometric read-out: (XL665
emission/Eu Cryptate emission)X10,000.
IFNα2b AlphaLISA Assay for TLR7 or TLR9 activity
[0409] After thawing the assay plates, 6µL of supernatant samples were transferred to a
low-volume AlphaPlate 384SW (Perkin-Elmer). The concentration of IFNα in supernatants
was measured using the IFNα
2b AlphaLISA Assay (Perkin-Elmer: AL297F). 3µL of IFNα acceptor beads/biotinylated antibody
solution was added first, using laboratory automation. After an hour incubation, 3µL
of streptavidin acceptor bead solution was added. The plates containing this mixture
were incubated in the dark for an hour and read on an appropriate plate reader at
reading parameters set by the manufacturer. (Envision, EnSpire: Perkin-Elmer).
THP-1 TLR8 Antagonist TNFalpha TR-FRET Assay
Cell-based assay:
[0410]
- 1) THP-1 cells were cultured in RPMI 1640 with 10% FBS, 10 mM HEPES, 1 mM Sodium Pyruvate,
1% Penicillin-Streptomycin L-glutamine, and 1% Non-Essential Amino Acids;
- 2) 3 sets of different passages of THP-1 cells in assay media were pooled, counted,
and resuspended in the same media as culture media, but with 5% FBS;
- 3) Cells were diluted to 100,000 cells/well (30 µl/well) and the R848 agonist was
diluted to 25 µM in 10 ul/well in media;
- 4) The cell and agonist dilutions were combined and 40 µl/well were added to 384-well
flat bottom Greiner assay plates containing test compounds in DMSO, which were Echo
pre-spotted at 50 nL per well with a 8 mM top dose and 10 point 1:3 serial dilutions
- 10 µM final top dose;
- 5) The plates were incubated overnight for 18-20 hrs at 37 degrees with 5% CO2;
- 6) The plates were then centrifuged at 1000 rpm for 2 min at rt;
- 7) 10µl/well of supernatants were transferred to 384-well low volume white Greiner
proxiplates; and
- 8) TNFα levels were measured using the TR-FRET assay described below.
TNFalpha TR-FRET Assay:
[0411]
- 1) Cisbio Human TNFalpha kit, 20,000 tests (62TNFPEC), and Greiner Bio-One LIA-white
TC 384 well small volume plates (cat # 784080) were used;
